Awoke this morning and checked my Motion for new messages. There was a symbol at the top left corner of the phone. Pulled down the menu and saw a message which said "SD Card Blank or has unsupported file system." I have rebooted the phone twice and am still getting this message. Checked to see if my photos were there, and they were, so I do not understand why I am getting this message. If I allow the phone to reformat the SD card, it will erase what is on the card. What is wrong and how do I fix it? Never saw this message before and have done nothing out of the ordinary/usual with my phone. Thanks!
